How is the AHfusion used to calculate the mass of solid that 1kJ of energy will melt? O A. 1kJ * AHfusion A Hfusion x g/mol solid B. 1kJ x 1/ AHfusion * g/mol solid O C. 1kJ x 1/A Hfusion * mol/g solid D. 1kJ * AHfusion x mol/g solid

Explanation:

Latent heat of fusion is the amount of heat required to convert 1 mole of solid to liquid at atmospheric pressure.

If is used to melt = 1 mole of solid

1 kJ of energy is used to melt =

Now if molar mass of  solid is x g/mol

Then mass of solid will be =

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
